Fan Shaped Rubber Strip

Product Introduction

This series of fan-shaped rubber expansion joint strips is a specialized waterproof sealing accessory developed for building expansion joints, settlement joints, and deformation joints. It is made of EPDM rubber or chloroprene rubber as raw materials and is extruded into a wave/fan-shaped structure using an integrated molding process. It can freely expand and contract with the deformation of the building structure, and has multiple functions such as waterproof, anti-seepage, dustproof, and buffering. It is widely used in engineering scenarios such as bridges, building exterior walls, roofs, tunnels, etc.

Core Features

Fan shaped wave structure, with a unique fan-shaped/wave shaped design that adapts to structural deformation requirements, can freely deform with the expansion, settlement, and displacement of the building structure, effectively absorbing the stress generated by structural deformation, avoiding the failure of rubber strips due to tension and compression cracking, while maintaining continuous sealing at the gaps, completely solving the problem of expansion joint leakage.

High quality rubber material, long weather resistance and durable life Selected ethylene propylene diene monomer (EPDM) rubber or neoprene raw materials, excellent high and low temperature resistance, UV resistance, aging resistance, ozone resistance, long-term exposure to outdoor environment is not easy to harden, shrink, crack, can work stably in a wide temperature environment of -40 ℃~120 ℃, long service life, reduce later maintenance costs.

Excellent waterproof and anti-seepage performance, high protection level. The rubber material itself has good water resistance and anti-seepage performance. Combined with the continuous sealing design of the fan-shaped structure, it can effectively block rainwater and sewage from infiltrating into the expansion joint, while preventing dust and debris from entering the gap and causing blockage, protecting the structure from erosion, and improving the overall durability of the building.

Easy installation and strong construction adaptability. The product has flat fixed wings at both ends, which can be directly installed on both sides of the expansion joint structure through pre embedding, pressure strip fixation or bonding methods. The construction is convenient and suitable for expansion joint scenarios with different widths and deformations. Different specifications for wave height and wing edge width can also be customized according to engineering needs, with strong universality.

Buffer and shock absorption, protecting the elasticity of rubber materials in building structures, can absorb the impact force generated by building structure vibration and deformation, play a buffering and shock absorption role, reduce structural stress concentration, protect concrete and metal components around expansion joints from damage, and enhance the stability and safety of building structures.

Scope Of Application
